\=
matches the empty string, but only at point.
Heh, I didn't even know about that one...
Ah, yeah:
(defvar whitespace-point (point)
"Used to save locally current point value.
Used by function `whitespace-trailing-regexp' (which see).")
So that's basically the same problem I'm having here, and it's solved by
machinery that keeps that variable updated in whitespace buffers,
probably because font-lock doesn't provide that information?
